Put your cash away. When your pump motor dies or your pump itself just goes bad consider upgrading to an energy efficient pump motor. Now you don’t have to replace the entire pump to upgrade to an energy efficient unit. There are now energy efficient motor models that bolt right up to your existing pump housing. This is cost less than buying a whole new energy efficient pump. However if you have the extra cash I would highly recommend that you go with an entire new energy efficient pump unit the reason being is although you can hook up an energy efficient motor directly to your existing unit the water flow design of the new energy-efficient pumps are such a way that the water flow itself is designed to be more energy efficient you will save money by using a energy efficient motor that bolts right up to your existing pump but you’ll save even more if you replace the entire pump unit with an energy efficient pump. energy efficient pumps are a little bit more money up front but you’re not going to get rid of your pool are you? you’re probably going to have it for a long time. The average life of a of a motor is between 8 and 12 years that’s a long time to go without an energy efficient unit that can cut you power cost by up to 70%.
